– 9 yr old FS Boxer with history of confirmed mammary carcinoma diagnosed this past December
– new mass found in region of left thyroid gland – FNA showed brownish fluid and cytology consistent with a cyctsic structure with low cellularity
– u/s of neck shows a cystic structure in the region of the L thyroid gland – normal gland cound not be found
– the right thyroid gland is normal
– I had a case once where cystic structures were found in the neck and were removed and shown to be ectopic thyroid carcinoma

– would this be concerning for thyroid carcinoma, parathyroid neoplasia, other?

Looking at my first still
Looking at my first still above, now I am wondering if I do see some thyroid tissue, proving thst this is coming from the thyroid? I labelled it below:
From Atlas of of Small Animal
From Atlas of of Small Animal Ultrasonography (Penninck/Anjou)
“Thyroid glands occasionally contain cysts with distal acoustic enhancement. These cyst can be confused with normal parathyroid glands, which can also appear hypoechoic or anechoic. The cyst may be irregular in shape, but its margin should be visible in both planes. Thyroid and parathyroid neoplasia, sush as thyroid cystadenoma and parathyroid adenocarcinoma, can also appear cystic (phillips et al. 2003
For what it is worth
yep… carcinoma’s have hot
yep… carcinoma’s have hot doppler flow typically and this has flow around it and you can see the thyroid capsule encompassing botht he normal tissue to the left of your image and continuing around the cyst. looks pretty benign but you can drain it if need be or surgically remove it. I doubt there is any abscessation because there is no inflammatory pattern around it.
I have recommended surgical
I have recommended surgical removal and histopath with pre-surgical CT if the client can afford it. Anyone have experience with chemical ablation?
